Voice cabling is the wiring of a building which
enables basic telecommunications systems including land-based phone lines,
modems, or analog lines. These copper or fiber cables carry data across long
distances and are increasingly designed to transmit greater amounts of data at
Voice cabling is the primary step in installing a land-based phone line, modem
or analog line. This wiring is essential for telephone cabling as well as for
other network applications that allow for spoken communication or other voice
services over long distances. Voice cabling uses voice-grade wire and standard
telephone jacks to connect telephone landlines to local communication systems.
There are several types of
voice cabling, and newer varieties have been developed in recent years to
comply with national and global communication technology standards.
Category 1 cabling was a
common type of land-line cable that is no longer recognized by the
Telecommunication Industry Association. It was used for basic telephone
communication and doorbell wiring.
Category 3 cable is a
copper, unshielded twisted pair cable created to transmit up to 10 mb of data
per second, and is the current voice cabling standard.]
Category 5 cabling is
another commonly used unshielded twisted pair cable designed for high signal
reception that allows for far-end communication.
